High-Speed Over-current Detection

This high-speed, low-side over-current detection solution is implemented with a single zero-drift fast-settling amplifier (OPA388) and one high-speed comparator (TLV3201). This circuit is designed for applications that monitor fast current signals and over-current events, such as current detection in motors and power supply units. The OPA388 is selected for its widest bandwidth with ultra-low offset and fast slew rate. These parameters allow the circuit to be a well-balanced, high-speed solution in order to accurately detect high frequency current components. In applications that only require average current detection, devices with less bandwidth can… Read More

Motion Sensing & LED Control

Reference Design Description The Motion Sensing & LED Control Reference Design demonstrates how to use Zilog’s Z8FS040 ZMOTION MCU with the IXYS LDS8710 High-Efficiency LED Driver and explains how to implement features such as ambient light detection and LED dimming in addition to passive infrared motion detection. It also illustrates how the combined capabilities of both products are an exceptional choice for energy management functions in applications ranging from low-power displays and backlighting to ambient room lighting control. Features Integrated passive infrared (PIR) motion sensing and LED control combined in a single… Read More
